WMR200A Temp sensor battery life
« on: July 16, 2013, 04:01:09 PM »
Hello Forum,

I only get about a month out of the expensive AAA Energizer lithium batteries in the temp/humidity sensor. The solar panel appears to work fine as the wind speed/anemometer AA batteries have been in for almost a year and still going strong. I know both sensor modules share the one solar panel and the 3-cell battery pack in the solar panel measures almost 4 volts, so that is strong. I haven't opened the temp sensor to look deep inside yet and I also haven't swapped the two solar panel power plugs from the temp to the wind sensor. I have a bad feeling the solar power circuit is bad in the temp sensor, resulting in it draining the AAA lithium batteries prematurely, any thoughts? Thanks![/img]
